| UN R13: Proposal to amend trailer and towing-vehicle compatibility requirements |
| Reference Number: GRVA-20-32 |
|
Proposal to address loss of trailer friction braking efficiency due to increased use of robust endurance braking systems and electrification of trucks. The number of trucks with strong endurance braking systems and increasing electrification of vehicles with more efficient energy recuperating systems reduces the use of friction brakes. As a result, brake pads and linings in some commercial vehicles do not reach a temperature that is needed for the development of optimum brake performance. In particular in trailers, a loss of brake force develops due to brake pads and linings losing effectiveness – they “fall asleep” and need to be replaced although they are not worn out. |
